Naloxone (brand name “Narcan”) is an FDA-approved life-saving medication used to reverse an overdose from opioids: a) medications prescribed to treat pain, like methadone, codeine, morphine, oxycodone (Percocet), hydrocodone (Vicodin), fentanyl, hydrophone (Dialudid) and b) illegal drugs, like heroin and fentanyl.
Giving someone naloxone is similar to performing CPR. When you give it to a person who has overdosed on opioids, naloxone can bring them back to life and prevent them from dying of an opioid overdose.
Studies have shown how effective it is in saving a person’s life: naloxone can increase their rate of surviving by eight-fold (1), and survival rates after administering it are between 83-100%. (2)
Opioids bind to receptors in our brains, spinal cords, and GI tract, causing a variety of effects on our body, such as decreasing pain levels, altering our mood (causing a pleasurable, euphoric “high” feeling), slowing our breathing, and causing constipation.
When too many opioids are taken (“opioid overdose”), a person STOPS breathing. (AKA “respiratory depression.”). After only 3-5 minutes without oxygen, brain damage will start to occur, which could lead to death.
Naloxone works as an antidote, also known as an “antagonist” to the opioid receptor. When it is given to a person who has taken too many opioids, it pushes the opioids off the receptors, thus allowing that person to breathe again.
Since naloxone works as an antidote to an opioid overdose and quickly pushes opioids off their receptors, the person will experience immediate withdrawal--body aches, dizziness, weakness, nausea, stomach pain, diarrhea, fever, and chills. These symptoms are not pleasant, but naloxone will allow them to breathe again and SAVE THEIR LIFE.
So, while giving naloxone to someone will make them feel uncomfortable, having these uncomfortable feelings means it IS working.
If you give it to someone who does NOT need it or if someone accidentally consumes it who does not need it (like a kid), it will have NO effect.
Naloxone is considered very safe. There is a small possibility that someone could be allergic to naloxone (they develop hives or have swelling in the face, lips, or throat). This is true for ANY medication. If a patient experiences an allergic reaction, seek medical help immediately.
The “BIG PICTURE” is that an opioid overdose IS DEADLY. It only takes a few minutes of not breathing to cause permanent brain damage. Naloxone reverses this process and allows the person to breathe again.
People at risk for an opioid overdose include those who are:
NO. If someone overdoses on other medications or drugs-- like benzodiazepines (Xanax, Klonipin, Ativan, Valium), cocaine, methamphetamines-- Naloxone will not work. It only works for opioids.
Still, if you are not sure what the person overdosed on and there is a possibility that they overdosed on opioids, a good rule of thumb is to GIVE naloxone. The worst case scenario is it won’t do anything. The best case scenario is you can save someone’s life!
While opioids bind to opioid receptors and activate the “reward centers” creating a “high,” they also activate the respiratory center causing respiratory depression. These can look VERY similar. So, how do you tell the difference between a “high” and an overdose?
Signs of overdose:
Tip #1: Rub someone’s chest VERY hard (sternal rub). If you are able to arouse them/wake them up at all, they have NOT overdosed.
Tip #2 Let the person know you plan to “narcan them.” People who are in a high will NOT want narcan, as it will cause them to experience withdrawal symptoms. If they resist, they have NOT overdosed.
Tip #3 Bottom line: When in doubt, give someone NARCAN! If they have not overdosed, it will put them into withdrawal, but that’s just uncomfortable. If they have taken another (non-opioid substance), narcan simply won’t work. But if they have overdosed on opioids, YOU WILL BE SAVING A LIFE!
Keep in mind, if someone is not breathing, the most important thing to do is RESCUE breathing. Rescue breathing helps all types of overdoses as you wait for emergency personnel to arrive.
No, there are studies that show that reporting what drugs were used slows down response time (due to stigma associated with drug use). All you have to do is say that you see a “person is not breathing and turning pale”. Also note that the Good Samaritan law protects anyone who calls (even if the person who calls was also using drugs).
Yes! Once administered, naloxone can stay in the body from 30-90 minutes. Most opioids can stay in the system much longer than naloxone. So, once naloxone wears off, the opioid (that caused the overdose) can rebind to the opioid receptors and a person can overdose again. So, they might require multiple doses of naloxone.
A person is not considered “in the clear” until waking up and being observed for at least 2-4 hours.
It depends on the opioid consumed and how strong the opioid is. Overdose (respiratory depression) usually occurs 1-3 hours after a person takes the opioid. However, with stronger opioids like fentanyl (which is 50- 100 times as strong as heroin), overdose can occur within 2-5 minutes after consumption. A person can be walking around looking fine and then they can collapse suddenly.
This gives responders little time to intervene and why so many overdoses are occurring. If someone went to the bathroom 5 minutes ago and has not yet come out, they could have overdosed.
Your doctor can prescribe it to you.
It is also available at pharmacies without a prescription.
Most private health insurance plans, Medicare, and Medicaid cover it.
Policies may vary by state.
As of July 2020, in order to reduce opioid overdoses, the U.S. Food and Drug Administration recommends that naloxone be given to:
Additionally, since we are all potentially “first responders,” it is a good idea for everyone to carry naloxone on them and know how to use it.
Naloxone is available as a nasal spray, an injection into the muscle (“IM”), or into the blood (“IV”). The nasal spray is the formulation that people commonly carry with them and is easily administered.
Since it is very possible you could come into contact with someone who has overdosed on opioids at any point--while walking in your neighborhood, out shopping or running errands, at restaurant, at a gas station, using public transportation, at a party, etc, it is a good idea to carry naloxone. Anyone could be a potential “first responder!”
You should keep naloxone in a place that is readily accessible and that you won’t forget!
You should keep naloxone at a temperature between 40-104 degrees Fahrenheit and replace it if it is exposed to more extreme temperatures and/or the expiration date passes.
Yes, there are two ingredients in “Suboxone” and other brand name formulations used to treat opioid dependence.
